Size reduction is an important preparation step in many Animal by-product (ABP) and slaughterhouse rendering lines. It helps create a more consistent material stream before thermal processing, rendering, sterilization, or further treatment. WALDT helps organizations define the right pre-processing approach as part of a complete industrial solution — not as an isolated equipment decision. Rendering technologies must respect local legislative requirements such as Regulation (EC) No 1069/2009 of the European Parliament.
Animal by-product shredding means reducing larger or irregular by-product materials into a more manageable form before the next processing step. This may be required before cooking, rendering, sterilization, pumping, conveying, or further separation.
The right approach depends on the raw material, its composition, the target output, and the downstream process. Poultry, pork, beef, feathers, bones, soft tissues, fallen stock, or mixed slaughterhouse by-products may require different handling and preparation strategies.
Inconsistent particle size can make the overall process harder to control. It may compromise heat transfer, processing time, material handling, downstream equipment performance, and the quality of the final output.
A well-defined size reduction step can support more stable operation, better process control, and improved integration between raw material intake, thermal treatment, separation, odour treatment, and output handling.
We start by understanding the material stream and the business objective.
A Technology Study can define the technical basis for the size reduction and rendering process.
WALDT helps define how size reduction connects with the wider processing line.
We support the project beyond the concept phase.
